Tyrion Lannister

If I attach spidercraft to him, does that effect stack on to his character ability?  In other words, would I look at the hand, choose a card to put into play, then look at the hand again and discard a card?  I could see this being very powerful if it works.

No, as those are two conflicting, separate claim replaxement effects. I think (but am not sure), that in such case FP wold decide, which replacement takes effect.

If for example Tyrion attacked alone and i remove him by "The fleet from arbor".Win challenge.Will it work?

Don't think so. When the winner of the challenge was resolved, Tyrion wasn't attacking alone.

AttackED - attackING....

so what is the verdict on having Tyrion attack alone and then removing Tyrion from the challenge? If you win the challenge (that Tyrion attacked alone), do you get Tyrion's effect?

This is for better rules lawyers than me, but I'm pretty certain the game doesn't check Tyrion until claim resolution occurs.  His text only creates the effect after the challenge has been won. 

Edit: So that is the to say, if you take him out with the fleet, the game has nothing to check.   If he's not the sole participant at the resolution, the game doesn't care about his text.  No claim replacement occurs.

Normak is correct.

No, it is a claim replacement effect that is independant of your claim value. It is a passive effect that replaces the standard frame Action of claim resolution (which is based on the type of challenge and the claim value of your plot card) with the effect of the card.

This also means that if your claim is zero his effect will replace the framework action (Where zero cards are affected) with the special claim effect, so he is good to use on Valar turns or when your opponent has Loyalty Money can Buy revealed.

what does if able in that case means?

I think it means, that you can't put into play a event card or a unique card which is in your dead pile

Hey ! I am fairly new to agot lcg and I wanted to ask how this card works. For example: I am attacking with tyrion, then  I reveal a random card of the opponents hand which is f.e. robb stark. Now I can bringt robb stark into play under my control and when I havent attcked this turn with military I can attack with robb stark afterwards?

When you put a card of your opponent's into play under your control, that card behaves just as if it came from your deck. So yes, you can attack, defend, use its abilities, etc. with the card you get from Tyrion's ability once it is put into play the same as you would any other card from your deck.

why this card isn't in use in any deck ?! this is amazing strong, isn't it?! 

Because there are at least 2 other versions of Tyrion that are just as good (if not better in a lot of decks). And because you are just as likely to pull an event or an attachment that you can't use as you are a character, location or attachment that you can. And because the Prized 2 on this version of Tyrion makes him a huge target for your opponent and awfully hard to play (because you have to put EVERYTHING into keeping him alive at certain times).

He is very strong, yes, but he has significant disadvantages, too.
